Diseases And Immunity Continued
Akopọ
Cholera can turn a healthy person dangerously ill within hours, not by destroying tissue, but by a single clever toxin that hijacks the way water moves in the gut. It is a striking case study in how a microscopic bacterium, contaminated water and the physics of osmosis combine to cause disease.
This is an Extended-tier topic. In this lesson you will learn what cholera is and how it spreads, and then follow the exact chain of events by which the cholera toxin causes the severe, watery diarrhoea that makes the disease so dangerous.
Awọn Afojusun
- [Supplement] Describe cholera as a disease caused by a bacterium which is transmitted in contaminated water
- [Supplement] Explain that the cholera bacterium produces a toxin that causes secretion of chloride ions into the small intestine, causing osmotic movement of water into the gut, causing diarrhoea, dehydration and loss of ions from the blood
